Abstract :
A new high-speed redundant CORDIC processor with constant scaling factor is designed. Compared to previously proposed redundant CORDIC methods, the new processor not only preserves the constancy of the scaling factor, but also performs the scaling operation within the regular iterations. Thus, the processor does not require any complicated division/square-rooting operations, extra correcting iterations, or additional scaling iterations. VLSI implementation result of the new redundant CORDIC processor is also included
